The UFC 166 main card airs on pay-per-view following prelims on FOX Sports 1 and Facebook.

The first fighter steps on the scale at 4 p.m. CT local time, and doors open to the public at 3 p.m. The weigh-ins are free and open to the public.

Prior to the weigh-ins, fans can attend a Q&A session with top lightweight contender Josh Thomson, who in December will meet champion Anthony Pettis for the title at UFC on FOX 9 in Sacramento. He got his shot at Pettis in part thanks to the continued injury to T.J. Grant, but also based on his April “Knockout of the Night” win over Nate Diaz in his first UFC fight in nearly nine years. In May 2012, Thomson lost a split decision to Melendez for Strikeforce’s lightweight title.

The Q&A is open to members of the UFC Fight Club. Doors for the Q&A open to Fight Club members at 1:30 p.m. CT with the Q&A taking place at 2 p.m. CT.

A total of 26 fighters got their chance to shine on Saturday as part of UFC 190 at Rio de Janeiro’s HSBC Arena. Now that UFC 190 is in the books, it’s time to commence MMAjunkie’s “Three Stars” ceremony.

The man known for cranking submissions to the point of injury added eye-gouging to his repertoire. But is the controversy of Rousimar Palhares too essential to his bizarre, awful appeal for his employers to take any meaningful action against him?
